As shown in Fig. 3 and 16, slug arrester 14 is equipped in the slug dust trapping chamber 11, slug arrester 14 is arranged in section Dust trapping chamber 11 is filled in close to one end of slug catcher 2, and slug arrester 14 is welded by multiple plates according to certain angle, more A wavy setting of plate, the top of slug arrester 14 are h3 away from the distance of partition 3, and the lower end of slug arrester 14 is away from de- The distance of water pot inner wall is h4, and the top of slug arrester 14 is set away from the distance h3 of partition 3 according to the treating capacity of gas-liquid mixture Fixed, when the treating capacity of gas-liquid mixture is high, the distance of h3 is small, and when the treating capacity of gas-liquid mixture is low, the distance of h3 is big, together When slug arrester 14 lower end set away from the distance h4 of dehydration top tank structure according to gas-liquid mixture liquid content, work as liquid content The distance of Gao Shi, h4 are big, and when liquid content is low, the distance of h4 is small.Slug arrester 14 is set, slug flow can be made gradually to disappear It loses, forms stratified flow, keep the gas-liquid separation effect of gas-liquid mixture more significant.

A kind of operational process of the anti-slug eddy flow dehydration device of high-liquid-ratio gas well well head is as follows:

As shown in figure 4, gas-liquid mixture enters in drain sump from first entrance 1, compartment 13 is arrived first at, in compartment In 13 after the trapping of slug catcher 2, liquid under the effect of gravity, while falling under the action of slug catcher 2, into every The slug dust trapping chamber 11 of 3 lower section of plate, and gas then enters the dewatering station 12 of 3 top of partition, thus realizes gas-liquid mixture Gas-liquid separation for the first time, the liquid after separation are discharged through the first liquid phase capturing device 5, and the gas after separation enters dewatering station 12, this When, moisture can be contained in gas, gas enters circulation eddy flow dehydration device 4 under the action of air-flow and carries out second dehydration, specifically , gas enters dehydrating tube 16, flows under the action of air-flow along dehydrating tube 16, when by water conservancy diversion axis 18, in water conservancy diversion leaf So that air-flow is generated rotation in dehydrating tube 16 under the action of piece 19, rotating flow is become from axial circulation, i.e., by along 16 axis of dehydrating tube The axial flow of line direction movement is changed into the swirling eddy around the rotation of 16 axis of dehydrating tube, at this point, air-flow generates tangential velocity, It is rotated in dehydrating tube 16 around the axis of dehydrating tube 16, air-flow is made to generate centrifugal force, under the influence of centrifugal force, the intracorporal liquid of gas Body (including heavy phase liquid water and part heavy constituent) is thrown toward the inner wall of dehydrating tube 16, makes the gas (gas-liquid for the first time containing moisture Gas after separation) realize secondary gas-liquid separation, the gas after secondary separation enters downstream chamber 8 through dehydrating tube 16, finally by First outlet 7 is discharged, and the liquid that 16 inner wall of dehydrating tube is thrown toward after secondary separation continues to flow along the inner wall of dehydrating tube 16, through de- The second outlet 15 of 16 tail portion of water pipe enters in diversion chamber 17, and the inlet 10 then through 17 bottom of diversion chamber enters liquid collecting room 9, most it is discharged afterwards through second liquid phase capturing device 6, and enter in diversion chamber 17 at this time, there are also portion gas, into diversion chamber Gas in 17 then passes sequentially through circulation pipe 20 and water conservancy diversion axis 18, is again introduced into dehydrating tube 16 and is dehydrated.

As shown in figure 5, the power resources of circulation eddy flow dehydration device 4: when gas enters dehydrating tube under the action of air-flow After 16, when by water conservancy diversion axis 18, negative pressure is generated in water conservancy diversion axis 18 under the action of air-flow, the circulation being connected at this time with water conservancy diversion axis 18 It is negative pressure in pipe 20 and diversion chamber 17, negative pressure is also generated at the second outlet 15 of 16 tail portion of dehydrating tube, under the action of negative pressure Gas in dehydrating tube 16 enters diversion chamber 17, completes the circulation in circulation eddy flow dehydration device 4.

Above-mentioned technical proposal is a kind of embodiment of the utility model, for those skilled in the art, On the basis of the utility model discloses application method and principle, it is easy to various types of improvement or deformation are made, without It is only limitted to method described in the above-mentioned specific embodiment of the utility model, therefore previously described mode is only preferred, and Not restrictive meaning.
